摘要
利用ＰＣ微机的并行打印口和ＭＰ－１溶出分析仪的绘图仪端口，通过接口电路实现微机对ＭＰ－１仪的数据采集；在对读入微机的极谱信号进行预处理后，用联机卡尔曼滤波方法实现了Ｉｎ、Ｃｄ重叠极谱波的分辨。结果表明，当Ｉｎ、Ｃｄ两组分相对浓度比为１：１６～１３：１时，在本联机系统上可满意地用卡尔曼滤波法实现双组分同时测定。
By using the parallel printing I/O port of PC microcomputer and the graph plotter port of MP-1 stripping analyzer, an interface circuit was designed for data acquisition. After the pretreatment of the polarographic signals, Kalman Filter was used in resolution of the overlapping polarographic waves of mixtures of in and Cd. The results showed that when the relative concentration of in and Cd was 1: 16 to 13: 1 , the satisfactory quantitative results of two components can be obtained with this on-line microcomputer based Kalman Filter.Some parameters in the process of Kalman Filtering were discussed as well.
